Grrr, I hate top posting. So hard to add inline and following Anyway, several points. We don't know it should be a ufsdump, your dumptype includes global that we don't see and otherwise does not define PROGRAM. You keep using a blocksize of 64k for dd, why? Amanda normally uses 32k. Have you read the docs refered to above for how to recover? Your dumptype says compress, presumably with gzip. I see no unzipping in your attempted recovery commentary. Following an mt rewind, the first thing a dd should see is the tape label header file. Your output is certainly NOT an amanda tape label. Are you certain this is a valid amanda tape? Or you showed the sequence of commands accurately? Solaris has a fine file(1) command. What does "file /tmp/data" tell you about what dd pulled from the tape? -- Jon H.
